A cross between a folded-eared cat and an erect-eared cat may not necessarily cause the disease, but the chance of the disease will be higher. As long as cats carry the folded ear gene, they have a certain chance of developing the disease. Cats bred from folded-eared cats and folded-eared cats will have a particularly high chance of developing the disease and will be more serious. Cats bred from folded-eared cats and prick-eared cats will have the disease. The probability will be relatively low, but with current science and technology it is impossible to determine whether a cat with folded ears will develop the disease.

Precautions for breeding Fold-eared cats

1. Fold-eared cats cannot be bred with inbreeding. Generally, if a fold-eared cat mates with another fold-eared cat, it is easy to give birth to a problematic cat baby. When folded-eared cats mate and breed with each other, the bone defects in their ears are magnified, which can easily lead to physical defects in the offspring.

2. Scottish Fold cats can be bred and mated with American shorthair cats and British shorthair cats; you can also choose Fold cats with erect ears to mate. Cats born in this way should have ears that are upright and folded, but the cats' bodies are very healthy.

3. When Scottish Fold cats mate, owners should prepare a quiet and comfortable space for them. Avoid outside interference and prevent strangers from entering and exiting at will and affecting the mating process of cats.
